Embodiments of the present disclosure provide a method for accessing abase station, which may be applied to a multi-mode terminal thatsupports a plurality of working modes. The multi-mode terminal may workin networks of different technical standards and support a plurality ofnetwork bands, that is, the multi-mode terminal supports a plurality ofworking modes.

FIG. 1 is a flowchart of a method for accessing a base station inaccordance with an exemplary embodiment, which may include the followingsteps.

In step 101, working mode candidates which are transmitted by aplurality of base stations and correspond to the plurality of basestations respectively are received, each of the working mode candidatesbeing a working mode in which the corresponding base station supports aterminal accessing thereto to work.

In step 102, a target base station matching the multi-mode terminal isdetermined from the plurality of base stations according to the workingmode candidates and a plurality of working modes supported by themulti-mode terminal.

In step 103, the multi-mode terminal accesses the target base station.

In the above embodiment of the present disclosure, the multi-modeterminal may first receive the working mode candidates transmitted bythe plurality of base stations, each of the working mode candidatesbeing a working mode in which the corresponding base station supportsthe terminal accessing thereto to work. Further, the multi-mode terminaldetermines a target base station matching the multi-mode terminal fromthe plurality of base stations according to the working mode candidatesand the plurality of working modes supported by the multi-mode terminalitself, and further accesses the target base station. Through the aboveprocess, the multi-mode terminal can select the target base stationmatching the multi-mode terminal from the plurality of base stations,and then access the target base station, thereby achieving the purposeof allowing the multi-mode terminal to work normally.

With respect to the step 101, a current base station may transmit aworking mode that supports the terminal accessing thereto to work, i.e.,a working mode candidate corresponding to the current base station, tothe multi-mode terminal in a coverage range of the current base station.Each base station may correspond to one or more working mode candidates,each working mode candidate corresponding to one carrier band. In anembodiment, the current base station may broadcast the working modecandidate in system information.

In this step, the multi-mode terminal directly may receive thecorresponding working mode candidates transmitted by the plurality ofbase stations directly according to related technologies.

With respect to the step 102, after receiving the working modecandidates which are transmitted by the plurality of base stations andcorrespond to the plurality of base stations respectively, themulti-mode terminal may determine the target base station matching themulti-mode terminal from the plurality of base stations according to theworking mode candidates and the plurality of working modes supported bythe multi-mode terminal itself.

An exemplary process of determining the target base station is shown inFIG. 2. FIG. 2 is a flowchart of a further method for accessing a basestation in accordance with the embodiment shown in FIG. 1, which mayinclude the following steps.

In step 102-1, a target working mode candidate matching any of theplurality of working modes supported by the multi-mode terminal isdetermined from the working mode candidates.

In this step, the working mode candidates corresponding to the pluralityof base stations respectively, which are received by the multi-modeterminal, may be as shown in Table 1.

TABLE 1 Base stations Working mode candidates Base station 1 Mode A andMode D Base station 2 Mode B Base station 3 Mode C and Mode D . . . . ..

The multi-mode terminal may determine a target working mode candidatematching any of the plurality of working modes supported by themulti-mode terminal itself according to Table 1. For example, theplurality of working modes supported by the multi-mode terminal areassumed to be Mode A and Mode E. Then, the multi-mode terminal maydetermine that Mode A is a target working mode candidate according toTable 1.

In step 102-2, a target base station matching the multi-mode terminal isdetermined from the plurality of base stations according to the targetworking mode candidate.

In the embodiment of the present disclosure, the step 102-2 may includethe following two cases.

In the first case, if the number of target working mode candidates isequal to 1: the multi-mode terminal may use the base stationcorresponding to the target working mode candidate in the plurality ofbase stations directly as a target base station matching the multi-modeterminal.

For example, the plurality of working modes supported by the multi-modeterminal include Mode A and Mode E, the number of target working modecandidates determined according to Table 1 is 1, and the target workingmode candidate is Mode A. Then, the base station 1 corresponding to ModeA is the target base station matching the multi-mode terminal.

In the second case, if the number of target working mode candidates isgreater than 1: the multi-mode terminal may select the target basestation according to current service requirements thereof.

First, the multi-mode terminal may determine a target working modecandidate matching the current service requirements from the pluralityof target working mode candidates. The service requirements may includea requirement for delay and/or a requirement for a carrier band.

For example, the plurality of working modes supported by the multi-modeterminal includes Mode A, Mode C, and Mode E, and the number of targetworking mode candidates determined according to Table 1 is 2, i.e., ModeA and Mode C, respectively. The current service requirement of themulti-mode terminal needs to ensure low delay, while Mode C in thetarget working mode candidates can meet the service requirement for lowdelay. Then, Mode C is the target working mode candidate matching thecurrent service requirement of the multi-mode terminal.

For another example, the plurality of working modes supported by themulti-mode terminal include Mode A, Mode C, and Mode E, and the numberof target working mode candidates determined according to Table 1 is 2,i.e., Mode A and Mode C, respectively. Mode A corresponds to a carrierband 1, and Mode C corresponds to a carrier band 3. When the currentservice requirement of the multi-mode terminal requires the multi-modeterminal to work on the carrier band 3, it may also be determined thatMode C is the target working mode candidate matching the current servicerequirement of the multi-mode terminal.

Further, the multi-mode terminal uses a base station corresponding tothe target working mode candidate matching the current servicerequirement as a target base station matching the multi-mode terminal.

For example, in the above embodiment, the number of target working modecandidates is 2, i.e., Mode A and Mode C, respectively. Mode C is thetarget working mode candidate matching the current service requirementof the multi-mode terminal. Then, the multi-mode terminal uses the basestation 3 as a target base station matching the multi-mode terminalaccording to Table 1.

In the above embodiment, when the number of target working modecandidates is equal to 1, the base station corresponding to the targetworking mode candidate is used as the target base station matching themulti-mode terminal. When the number of target working mode candidatesis greater than 1, the base station corresponding to the target workingmode candidate matching the current service requirement of themulti-mode terminal is used as the target base station matching themulti-mode terminal. Through the above process, the target base stationmatching the multi-mode terminal can be determined by the multi-modeterminal from the plurality of base stations, such that the multi-modeterminal can work normally after accessing the target base station.

With respect to the step 103, after determining the target base stationfrom the plurality of base stations, the multi-mode terminal maytransmit an access request for accessing the target base station to thetarget base station according to related technologies. The target basestation establishes a wireless connection with the target terminal onthe basis of the access request, thereby completing a process ofaccessing the multi-mode terminal to the target base station andensuring that the multi-mode terminal accesses to the target basestation matching the multi-mode terminal and may subsequently worknormally.

FIG. 3 is a flowchart of another method for accessing a base station inaccordance with the embodiment of FIG. 1. The method may further includestep 104.

In step 104, during the process of accessing the target base station orafter accessing the target base station, the plurality of working modessupported by the multi-mode terminal is reported to the target basestation, such that the target base station configures a target workingmode matching the multi-mode terminal on the basis of the plurality ofworking modes.

In the embodiment of the present disclosure, step 104 may be performedsimultaneously with step 103 or performed after step 103 is completed.That is, the multi-mode terminal may report the plurality of workingmodes to the target base station during the process of accessing thetarget base station or after accessing the target base station. Thetarget base station selects the most matching target working mode forthe multi-mode terminal from the plurality of working modes according toinformation such as a current service type of the multi-mode terminal.Further, the target base station may transmit target networkconfiguration information corresponding to the target working mode tothe multi-mode terminal according to a correspondence relationshipbetween a predetermined working mode and network configurationinformation. After performing the network configuration according to thetarget network configuration information transmitted by the target basestation, the multi-mode terminal may work in the target working mode,such that the multi-mode terminal can work normally.

Through the above process, the multi-mode terminal may report theplurality of working modes supported by the multi-mode terminal itselfto the target base station during the process of accessing the targetbase station or after accessing the target base station. The target basestation configures the matching target working mode for the multi-modeterminal, thereby further ensuring that the multi-mode terminal can worknormally after accessing the target base station.

FIG. 4 is a flowchart of another method for accessing a base station inaccordance with an exemplary embodiment, which may be applied to a basestation. The method includes the following steps.

In step 201, a working mode candidate corresponding to the base stationis transmitted to the multi-mode terminal, such that the multi-modeterminal determines a target base station matching the multi-modeterminal from the plurality of base stations according to the workingmode candidates that are transmitted by a plurality of base stations andcorrespond to the plurality of base stations respectively and aplurality of working modes supported by the multi-mode terminal, whereineach of the working mode candidates is a working mode in which thecorresponding base station supports a terminal accessing thereto towork.

In the embodiment, the base station may transmit the working modecandidate corresponding to the base station to the multi-mode terminal.The multi-mode terminal may determine a target base station matching themulti-mode terminal from the plurality of base stations according to theworking mode candidates that are transmitted by the plurality of basestations and correspond to the plurality of base stations respectivelyand the plurality of working modes supported by the multi-mode terminal.Through the above process, the base stations transmit the working modecandidates corresponding to the base stations to the multi-modeterminal, such that the multi-mode terminal determines the target basestation matching the multi-mode terminal, and ensures that themulti-mode terminal can work normally.

In an embodiment, the base station may transmit the working modecandidate to the multi-mode terminal by using system information. Thesystem information may be key system information or other systeminformation, wherein the key system information refers to minimum systeminformation required for the terminal to randomly access to the basestation, and the other system information refers to system informationother than the key system information.

In this step, the base station may carry a working mode candidatecorresponding to the base station in the key system information, andbroadcast the system information to the multi-mode terminal.Alternatively, the base station may carry the working mode candidate inthe other system information, and transmit the other system informationto the multi-mode terminal by means of broadcast or unicast. The basestation may correspond to one or more working mode candidates, eachworking mode candidate corresponding to one carrier band.

The multi-mode terminal may select a target base station matching themulti-mode terminal to access according to the received working modecandidates corresponding to the plurality of base stations respectivelyand the plurality of working modes supported by the multi-mode terminalitself.

In step 202, after the multi-mode terminal determines the base stationas the target base station matching the multi-mode terminal, theplurality of working modes supported by the multi-mode terminal, whichmay be reported during the process of accessing the base station orafter accessing the base station, is received.

In this step, after determining the current base station as the targetbase station, the multi-mode terminal may report the plurality ofworking modes supported by the multi-mode terminal during the process ofaccessing the base station or after accessing the base station, and thebase station then receives the plurality of working modes directly.

In step 203, a target working mode matching the multi-mode terminal isconfigured on the basis of the plurality of working modes.

In the embodiment of the present disclosure, in order to further ensurethat the multi-mode terminal can work normally, after receiving theplurality of working modes supported by the multi-mode terminal, thebase station may determine a most matching target working mode for themulti-mode terminal according to information, such as a current servicetype of the multi-mode terminal.

Further, the base station may determine target network configurationinformation corresponding to the target working mode according to acorrespondence relationship between a predetermined working mode andnetwork configuration information, and transmit the target networkconfiguration information to the multi-mode terminal. The multi-modeterminal performs network configuration according to the target networkconfiguration information, such that the multi-mode terminal can worknormally.

FIG. 5A is a schematic diagram showing a scenario of accessing a basestation in accordance with an exemplary embodiment. After receiving theworking mode candidates which are transmitted by a plurality of basestations 200 and correspond to the plurality of base stations 200respectively, a multi-mode terminal 100 determines a target base stationmatching the multi-mode terminal 100 from the plurality of base stations200 according to the working mode candidates and a plurality of workingmodes supported by the multi-mode terminal 100. Assuming that the targetbase station is 200-1, further, the multi-mode terminal 100 may accessthe target base station 200-1.

During the process of accessing the target base station 200-1 or afteraccessing the target base station 200-1, the multi-mode terminal 100 mayreport a plurality of working modes supported by the multi-mode terminal100 to the target base station 200-1. The target base station 200-1 mayconfigure a target working mode matching the multi-mode terminal 100 onthe basis of the plurality of working modes.

FIG. 5B is a flowchart of a method for accessing a base stationaccording to the scenario embodiment shown in FIG. 5A, which may includethe following steps.

In step 301, a base station 200 broadcasts a working mode candidatecorresponding to the base station 200 to a multi-mode terminal 100through system information.

The working mode candidate is a working mode in which the base station200 supports a terminal accessing thereto to work.

In step 302, the multi-mode terminal 100 determines a target basestation 200-1 matching the multi-mode terminal from the plurality ofbase stations 200 according to the received working mode candidatescorresponding to the plurality of base stations 200 and a plurality ofworking modes supported by the multi-mode terminal 100.

In step 303, the multi-mode terminal 100 accesses the target basestation 200-1.

In step 304, during the process of accessing the target base station orafter accessing the target base station 200-1, the multi-mode terminal100 reports a plurality of working modes supported by the multi-modeterminal 100 to the target base station 200-1.

In step 305, the target base station 200-1 configures the target workingmode matching the multi-mode terminal 100 on the basis of the pluralityof working modes.

In the above embodiment, the multi-mode terminal may select a targetbase station matching the multi-mode terminal from a plurality of basestations, and access the target base station, thereby ensuring that themulti-mode terminal works normally.

Further, the multi-mode terminal 100 may report the plurality of workingmodes supported by the multi-mode terminal 100 to the target basestation 200-1 during the process of accessing the target base station200-1 or after accessing the target base station 200-1. The target basestation 200-1 selects an appropriate target working mode for themulti-mode terminal 100. The multi-mode terminal 100 may perform networkconfiguration according to the target network configuration informationwhich is returned by the target base station 200-1 and corresponds tothe target working mode, and then work in the target mode, thereby alsoensuring that the multi-mode terminal can work normally.
